CVE-2026-107202
CriticalCVSS 9.1Summary
A command injection vulnerability exists in the h-ui (version v0.0.25 and below) administrative API due to improper validation of the listen configuration field. An authenticated administrator can submit a value containing shell metacharacters, leading to arbitrary OS command execution with root privileges.
Risk Assessment
An attacker with administrator privileges can execute arbitrary system commands, potentially leading to full system compromise.
Recommendation
Update h-ui to a version newer than v0.0.25 if a patch is available, or restrict access to the administrative interface.

Original NVD description (English source)
A command injection vulnerability exists in the h-ui (version v0.0.25 and below) administrative API due to improper validation of the listen configuration field. When an authenticated administrator submits a value containing shell metacharacters, the application constructs nftables/iptables rule strings using fmt.Sprintf and executes them via bash -c as root. Because the listen field lacks port or format validation, arbitrary OS commands can be injected and executed with root privileges.
